So, after selling my first born, I was able to afford all four OEM Autoride shocks for my 04 2500 Suburban 4x4. I would now like to level this eco friendly 8.1. The front sits at 36 and the rear is at 38 so in theory, I just need new keys to raise the front 2 inches. After reading countless threads, it seems that the super, ultra, mega Suspension Maxx $300 leveling keys are no better or worse than plasma selling, budget friendly $30.00 ebay/Amazon keys. My question(s) that I have are 1.) Do I need to get a kit that includes the shock relocation brackets and 2.) Do I need to get a kit that includes any rear suspension items?
